  • the slider 184 rotates on the top surface 102 of the inhaler device 100 with the rotational axis at the center of the top surface 102 of the inhaler device 100.
  • the user can open and close the first opening 52, the first air inlet hole 181A, and the second air inlet hole 181B by sliding the slider 184.
  • the chamber 50 receives the stick substrate 150.
  • the stick-side heater 40A heats the stick substrate 150 to generate the stick-side aerosol.
  • the second opening 56 is disposed at a position where the second opening 56 is in communication with an end surface (that is, an end surface of the substrate 151) of the stick substrate 150 inside the chamber 50 in a state in which the chamber 50 receives the stick substrate 150. Therefore, when the user holds the stick substrate 150 in the mouth and inhales, the air that has flowed into the chamber 50 through the second opening 56 flows into the inside of the stick substrate 150 from the end portion of the stick substrate 150 inside the chamber 50.
  • the air that has flowed into the inside of the stick substrate 150 is then mixed with the stick-side aerosol in the process of being conveyed via the inside of the stick substrate 150, and reaches the inside of the mouth of the user from an end surface (that is, an end surface of the inhalation port 152) of the stick substrate 150 outside the chamber 50.
  • a first airflow path 180A through which the first air inlet hole 181A and the second opening 56 are in air-communication with each other is formed as one airflow path 180 in the inhaler device 100.
  • the air that has flowed in through the first air inlet hole 181A is conveyed through the first airflow path 180A and flows into the internal space 80 of the chamber 50 through the second opening 56. Therefore, when the user adds the stick substrate 150 and inhales, air is conveyed along an airflow 190A and reaches, together with the stick-side aerosol, the inside of the mouth of the user
  • a second airflow path 180B through which the second air inlet hole 181B and the second opening 56 are in air-communication with each other is formed as one airflow path 180 in the inhaler device 100.

Therefore, when the user holds the stick substrate 150 in the mouth and inhales, air is conveyed along an airflow 190B and reaches, together with the mixture aerosol, the inside of the mouth of the user
  • the cartridge-side heater 40B is disposed, in the second airflow path 180B, at a position that does not overlap the first airflow path 180A.
  • the liquid guide 122 is also disposed, in the second airflow path 180B, at a position that does not overlap the first airflow path 180A. In other words, the cartridge-side heater 40B and the liquid guide 122 are not disposed in the first airflow path 180A.
  • Such a configuration prevents a flavor of the aerosol source guided by the liquid guide 122 from being added to the air conveyed along the airflow 190A. Consequently, when inhaling with the first airflow path 180A open and the second airflow path 180B closed, the user can taste the pure flavor of the stick-side aerosol whose flavor is not deteriorated due to the cartridge-side aerosol.
  • the slider 184 is one example of an opening/closing part that opens and closes each of the first airflow path 180A and the second airflow path 180B. As illustrated in FIG. 6 , the slider 184 can open the first airflow path 180A and close the second airflow path 180B by closing the second air inlet hole 181B. As illustrated in FIG. 7 , the slider 184 can open the second airflow path 180B and close the first airflow path 180A by closing the first air inlet hole 181A.
  • the sensor 112 further includes a hall sensor that detects the position of the slider 184.

  • the aerosol as liquid accumulated in the liquid reservoir 186 can be drained to the outside of the inhaler device 100 through the drain hole 162 via the drain path 166 by tilting the inhaler device 100 such that the drain hole 162 is placed on the lower side in a state in which the drain hole 162 is opened by the opening/closing valve 164.
